SPECIFICATION forming part of Letters Patent No. 365,699. dated June 28, 18187.

Application filed Apr-i121, .1887. Serial No. 235,654. (No model.) I

To a/ZZ whom it may concern:

Be it known that I, JACOB NOLF, a citizen of the United States of America, residing at New Maysville, in the county of Clarion and State of Pennsylvania, have invented certain new and useful Improvements in Stump-Extractors, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawing, and to .letters or iigures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in stump-extractors; and it consists in the construction and combination ofthe parts,as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawing, which illustrates my invention, the figure is a perspective view of a stump-extractor constructed in accordance with my improvement.

A refers to the frame, which consists of three uprights A, which are provided at their lower ends with shoes a a, which are attached to the ,lower ends of the uprights so as to be onaline with each other. The upper ends of the two outer uprights are beveled, so that the inner sides of these beveled portions will be parallel with each other, and through the upper ends, which are placed to be on a line with each other, passes a bolt, a', which will connect the upper ends of the three nprights securely to each other. l

At a suitable distance below the upper ends of the uprights or posts A bracebars b, which have their ends formed into eyes, are attached. The upper ends of the uprights A are further secured to each other by abail orloop, B, which is made of a single continuous piece or bar of metal of sufficient size to permit the same being passed around the upper ends ofthe uprights A', and provide a depending portion, b', which4 will extend below the-bolt a. This loop B,

when pressure is applied to its depending portion, will bind the upper ends of the uprights securely against each other, and as said upn rights diverge said loop cannot slip down u pon the same.

,XVithin the depending portion of the loop B is secured a link, c, through which passes a bail, C, said bail having its lower ends bent into eyes for engagement with linksd d, which engage with npwardly-projecting pieces d', which are securely attached by means of rivets to the parallel plates D D. The pieces d not Lonly provide a means for attaching the links, but also serve to keep the plates D separated from each other, so as toprovide a space through which t-he iiat bars E may pass. These bars E are provided at suitable intervals with perforations to receive su pportin g-pins c, which will rest upon the upper edge of said bars D when the stump extractor is being operated.

The lower ends of the perforated bars E E are pivotally attached to plates F F, and between the bars E is a perforated plate, f, to which a chain or other connection may be secured forl attaching thereto the weight or stump to be elevated. 'Io the outer ends of the plates F F are rigidly secured shanks G, to which are attached levers H II.

y Then it is desired to elevate'a stump or raise weights, the chain-or other connection is se cured to the weight or stum p, and by reciproeating the lever the pressure will be brought upon one of the pins while the opposite bar is elevated, and when said bar is elevated the pin `is inserted in the perforation immediately above the upper edge of the plates D, and by continuing the reciprocation of the lever and withdrawing and replacing the pins a large amount of leverage is obtained, which can be utilized for drawing stumps or raising weights.

I am aware that prior to my invention it was not new to attach perforated bars to a lever and have said bars extend through a plate at the upper portion of the supporting-frame; and I do not claim such construction as my invention, the object of my improvementbeing to bring the plate D down as low as possible, so that it will be easily accessible, so that the pins may be placed in the perforations by the person who operates the levers, and by constructing the parts as herein shown and described the device can be operated by a sina gle person.

I Claiinw" 1. The improved stump-extractor herein described, consisting of the uprights A', which are connected to each other at their' upper ends,

ICO

a loop, B, encircling the upper ends of said supports and provided with a depending portion, b', a bail, C, depending from said looped portion b and connected at its lower end to plates D, a lever, Il, having perforated bars E pivotally attached thereto, and pins for engaging with said perforated bar and the upper edge of the plates D, substantially as shown, and for the purpose set forth.

2. In a stumpextraotor, the uprights A', two of said supports having their upper ends beveled so as to be parallel with each other, and a connecting-bolt, a loop, B, which partially eneiroles the upper ends of said supports and is provided with a depending portion, b,

a bail, C, connected by means of links to the loop B and plates D, levers II, provided with Shanks G, to which are attached parallel plates F, said plates having centrally attached thereto a perforated plate, f, and perforated bars E E, theoparts being combined and organized substantially as shown, and for the purpose set forth. p

In testimony whereof I affix my signature in presence of two witnesses.
